Description

Technical field [0001] The invention relates to a portable element analysis device, in particular to a liquid cathode glow discharge emission spectrometry analysis device. Background technique [0002] The working principle of the liquid cathode glow spectrometer is as follows: Under normal pressure, with the solution as one electrode and the tungsten or titanium electrode as the anode, high voltage is applied to the two electrodes to cause the gas between the electrodes to discharge. During the discharge process, the solution in the liquid electrode is continuously vaporized, so that the metal ions dissolved in the solution also enter the plasma and are excited to produce an emission spectrum. The emission spectrum generated by the discharge is related to the solute component in the solution electrode, so it is possible to detect the metal ions in the solution through the detection of the emission spectrum. [0003] Such a device was published by Webb et al. in 2005 by simplifyin...
